THOMAS MOCROSSAN, OF WINNIPEG, CANADA.

WASHING- MACHINE.

SPEGIFICATION forming part of Letters Patent No. 516,443, dated March13, 1894. Application filed August 21, 1893. fierial No. 483,706. (Nomodel.) Patented in Canada September 5, 1893, No. 44,169.

To all whom it may concern/:-

Be it known that I, THOMAS MCOROSSAN, merchant, of the city ofWVinnipeg, in the county of Selkirk and Province of Manitoba, Canada,have invented certain new and useful Improvements in Washing-Machines,(patented in the Dominion of Canada September 5, 1893, No. 44,169 and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being made to the accompanyingdrawings, in which Figure 1. is a front elevation of a machine embodyingmy invention. Fig. 2. is an end view of the same; Fig. 3. a rear view.Fig. 4. is a horizontal section of cylinder 0 on the line of divisionbetween the two parts of the cylinder; Fig. 5. section on lines 1-2.Fig. 6. is a vertical section on line 56; Fig. 7. section on the line3-4. Fig.8. is a view of one of the short pieces of rope (enlarged).

My invention relates to improvements in washing machines by means ofwhich the cylinder containing the clothes and water is made to revolveupon hollow axes or tubes and is so arranged that the weight isdistributed according to the number of chambers in the cylinder. Theclothing is raised out of the water by shelves placed in the cylinderuntil they fall by gravitation and the remaining water is poured uponthem, and the corrugations of the interior cause the clothingcontinuallyto revolve upon themselves thus causing a thorough cleansing of thefabrics.

The details of construction, arrangement and operation are ashereinafter described.

In the drawings a is an ordinary frame or stand.

I) is a board fixed at one end to which the wringer may be attached.

0 is a cylinder which is divided by a central partition into twoseparated, equal-size compartments, which number is sufficient formachines intended for domestic use. Each compartment is intended toreceive'clothes independently of the other, and, in general,

clothes of one quality or fineness are placed in one compartment andthose of a different quality in the other. The axes, d d, of thecylinder are hollow, or tubular, to admit the injection of steam or hotwater.

e is a small cog wheel or pinion, secured to cl.

f is a larger cog wheel secured to the frame by the fulcrum pin j.

g is an ordinary ratchet lever working on the fulcrum j and having thesmaller lever it working on the fulcrum c which is connected with theratchet t" by the rod 8 (Fig. 1). The upper portion of the cylinder 0 isconnected with the lower by the hinges k. is. Fig. 3; and in the frontthe double spring catch p. p. is secured to the lower portion of thecylinder 0 with apertures at their upper end which admit the pins q. q.in the upper portion of the cylinder thus holding-the parts closelytogether. The cylinder compartments are corrugated internally ontheparallel sides as well as the periphery, as shown at 0, Figs. 2 and6.

At the joint line of the cylinder are shelves n. n. and Z Z which hold acertain quantity of water in the cylinder when the cylinder is turnedand prevent its coming out the shelves n. n. Fig. 7 are plain andstraight occurring at the joint as shown; the shelves Z Z which occupy asimilar position in the other compartment have a forked apron attachedto or forming part of them as shown in Figs. 5 and 6. Apertures at thebottom of the cylinder at r. r. are intended to draw ofi the water andmay be fitted with ordinary taps or plugs. The ends of the shelves land1 are united or joined to the sides of their respective compartments sothat no water can pass at that point. One shelf, Z or n, lies in closecontact with another, Z or n, and in practice they are about six inchesin width. The pairs of shelves, Z Z, and H, are opposite each other, andthe division plates, or m, also opposite each other, but in alternationwith the shelves, that is to say, at points removed seventy degrees fromthe shelves, as shown.

Divisions m. m. are placed at right angles to the shelves abovementioned so that in the act of rotation a portion of the clothing iscarried up at a time and in due course is precipitated to the bottom bygravitation so soon as the shelf reaches the proper angle and a portionof the water, that which is retained by the apron pieces flows betweenthe forks and falls upon them; and so on. It will be seen that by thearrangements of hollow axles and plugs the water may be drawn off oradded without removing the clothing and water or steam may be injectedwhile the cylinder revolves. It is also evident that the lever 9 withthe wheels f and e may be removed and the machine worked, by steam,electric or other power with the ordinary pulley and band or chainconnections. And further that in cylinders having a greater number ofcompartments they may be divided into any nu mber of convenient parts byas many shelves as may be required. Washing is further facilitated in myinvention by the introduction of short pieces of hard twisted ropesecurely bound at either end Fig. 8 which are placed loosely between theseveral articles to be washed and take the place of the old hand work,the number of pieces of rope employed depending on the size andcharacter of the things to be washed.

In operation of the machine, as the cylinder rotates, the clothes in onecompartment are being raised while those in the other compartment fallback into the suds at the bottom, so that the weight of the entirecollection of clothes in the two compartments is never lifted atoncewhich obviously enables the machine to be worked with acorresponding reduction of power. There is no leakage at the pointbetween the meeting surfaces of the parts Z Z and 'n 11., since water isnot filled into the cylinder to depth sufficient to overflow said parts,save as the cylinder rotates. The shelves Z take up a quantity of waterat each rotation and gradually discharge it upon the clothes as theyriseabove the latter.

What I claim is- 1. In a washing machine of the class described, thevertical, rotatable cylinder having two vertical compartments arrangedside by side, one being provided on its inner periphery with divisionplates, m, and the other with division plates, 'n, which are arranged inalternation with those (m) of the other compartment, whereby the clothesin one compartment are raised as those in the other fall, as shown anddescribed.

2. In a washing machine of the class described, the vertical, rotatablecylinder having its interior corrugated on all sides, and containing thetwo pairs of shelves 1 Z and ll arranged oppositely and adapted to takeand discharge water, and the division plates m m, also arranged oppositeeach other and in alternation with the said pairs of shelves, as shownand described.
